Product details

Overview

ZXTP5401ZTA from Diodes Incorporated is a 150V PNP high-voltage transistor in SOT89 package, rated for -600mA continuous collector current and -150V V_CEO, with V_CE(sat) < -0.5V at -50mA. It delivers low saturation voltage and 1.2W power dissipation, suited for high-side switching in industrial power supplies and DC-DC converters.

For engineers reviewing the ZXTP5401ZTA datasheet, ZXTP5401ZTA pinout, ZXTP5401ZTA application, or ZXTP5401ZTA equivalent, key selection criteria include verified -150V breakdown rating, SOT89 thermal performance on 25mm² copper, complementary pairing with ZXTN5551Z, and AEC-Q101 readiness for automotive-grade designs.

Technical Context

This PNP bipolar junction transistor operates with emitter-grounded configuration and supports linear and switching modes. Its BV_CEO = -150V and BV_CBO = -160V enable robust operation in high-voltage rails up to -120V collector-base bias.

With f_T = 100MHz and h_FE = 50–240 across -1mA to -50mA, it maintains usable gain at moderate frequencies while sustaining fast switching (t_d = 386ns, t_f = 275ns) under pulsed conditions per Note 6.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-150V - Withstands 150V reverse collector-emitter voltage before breakdown, enabling use in 100–120V DC bus switching stages.
I_C (cont.)	-600mA - Supports sustained load currents up to 600mA in high-side switch configurations without derating at 25°C.
V_CE(sat)	< -0.5V @ -50mA - Ensures ≤0.5W conduction loss at 50mA, critical for efficiency in low-duty-cycle control circuits.
P_D	1.2W - Maximum steady-state power on FR4 PCB with 25mm × 25mm 1oz copper; requires thermal pad layout per SOT89 outline.
f_T	100MHz - Enables stable amplification or switching up to ~10MHz square-wave signals with controlled edge fidelity.
h_FE	50–240 - Gain range validated at -1mA to -50mA, supporting predictable base drive sizing across operating current bands.

Pinout & Package

Package: SOT89 - Surface-mount plastic package with exposed emitter tab for thermal conduction; 0.05g mass; UL 94V-0 rated molding compound; moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	High-voltage input node	Connected to negative rail or load return; rated for -160V V_CBO; largest metallization area in SOT89 top view.
Emitter (E)	Common reference / heat sink node	Internally bonded to exposed metal tab; must be soldered to PCB copper pour for thermal management and current return path.
Base (B)	Control input	Receives negative bias current to turn on; V_BE(sat) = -0.7V to -1.0V defines required driver swing and current sourcing capability.

Key Features

Feature	Design Value
High-voltage blocking	BV_CEO = -150V enables direct interface with 100V+ industrial DC buses without external clamping.
Low-loss switching	V_CE(sat) ≤ -0.5V at -50mA reduces conduction losses by >40% vs. standard PNP transistors in same package.
Thermal reliability	R_θJA = 104°C/W on 25mm² copper allows 1.2W operation up to +75°C ambient without heatsink.
Automotive-ready construction	Fully RoHS-compliant, halogen/antimony-free, and manufactured in IATF 16949 facilities per Diodes' quality definitions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZXTP5402ZTA	V_CEO = -200V, I_C = -500mA, V_CE(sat) = -0.65V @ -50mA	Higher voltage margin but lower current rating and higher saturation loss	Select when system transients exceed -150V but load current stays below 500mA.
DZT5401	V_CEO = -150V, I_C = -600mA, V_CE(sat) = -0.45V @ -50mA, improved h_FE consistency	Direct replacement with tighter parametric spread and enhanced thermal stability	Preferred for new designs requiring long-term supply continuity and reduced binning variance.

Compared with ZXTP5401ZTA, ZXTP5402ZTA trades current capability for higher voltage headroom, while DZT5401 improves saturation voltage and gain consistency-making it the recommended upgrade path where design refresh is feasible.

FAQ

Is ZXTP5401ZTA qualified to AEC-Q101?

Yes-ZXTP5401ZTA is manufactured in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements for automotive-grade bipolar transistors. Full qualification documentation is available upon request through Diodes' automotive support channel.

What is the recommended PCB layout for thermal performance?

Use the SOT89 suggested pad layout from Diodes' package outline document, including a minimum 25mm² copper pour connected to the emitter tab via ≥4 thermal vias (0.3mm diameter). Maintain 1.6mm FR4 thickness and single-sided 1oz copper for the specified R_θJA = 104°C/W.

Can ZXTP5401ZTA replace ZXTN5551Z in complementary circuits?

No-ZXTN5551Z is its NPN complement, not a replacement. They are designed as matched pairs for push-pull or H-bridge output stages. ZXTP5401ZTA serves only PNP roles; substituting it for an NPN device would invert logic and cause circuit failure.

Why is ZXTP5401ZTA marked "not recommended for new designs"?

Diodes recommends DZT5401 as the next-generation replacement due to tighter V_CE(sat) distribution (-0.45V vs. -0.5V), improved h_FE consistency, and extended lifecycle support. ZXTP5401ZTA remains fully available and supported for legacy production and repair, but DZT5401 offers superior parametric stability for new schematics.
